-SiSU is an object-centric, lightweight markup based, document structuring,
-parser, publishing and search tool for document collections. It is command line
-oriented and generates static content that is made searchable at an object level
-through an SQL database.
+SiSU parses a lightweight-markup source into an abstract document object
+model. Every substantive element (paragraph, heading, table, verse, image)
+becomes a typed object carrying its position in the document's sequence
+and hierarchy, and a stable citation number. From that single abstraction
+it emits multiple output formats - HTML (segmented and scroll), EPUB3,
+LaTeX (then PDF via xelatex), ODT, plain text, and an SQLite full-text
+search database. Each object's number stays stable across every output
+format and across translations of the same document.
-SiSU markup helps define (delineate) objects (primarily various types of text
-block) which are tracked in sequence, substantive objects being numbered
-sequentially by the program for object citation. Breaking document into numbered
-objects provides interesting possibilities. These object numbers provide the
-possibility of citing/locating text precisely across different document formats
-and different languages (assuming the document has been translated). For search
-it also makes it possible to identify precisely where within in each document
-search criteria is met in the form of an index. Additionally the use of objects
-(and that objects are numbered) frees the possibility to represent the document
-in the manner considered most suitable to a specific document format (whilst
-retaining its structural (and citation) integrity).
+The processing pipeline is markup → abstraction →
+output.
-Objects which include their inherent associated properties (which vary by type
-of object), constitute building blocks of a document from which alternative
-representations of a document can be (imagined and) built.
+Object-Centric Document Abstraction. The abstraction stage builds an
+in-memory object model: every paragraph, heading, table, footnote and so on is a
+numbered object that carries its own parent / sibling / type metadata, known as
+OCN (Object Citation Numbering). Every output format is generated from that
+single abstraction, so all formats share the same object identifiers. The
+abstraction can also be written out as a human-readable, PEG-parsable text
+format (

-SiSU is an object-centric, lightweight markup based, document structuring, -parser, publishing and search tool for document collections. It is command line -oriented and generates static content that is currently made searchable at an -object level through an SQL database. -Markup helps define (delineate) objects (primarily various types of text block) -which are tracked in sequence, substantive objects being numbered sequentially -by the program for object citation. -
- --Summary. An object is a unit of text within a document the most common -being a paragraph. Objects include individual headings, paragraphs, tables, -grouped text of various types such as code blocks and within poems, verse. -Objects have properties and attributes, of particular significance are headings -and their levels which provide document structure. A heading is an object with a -heirarchical value, that conceptually contains other objects (such as paragraphs -and possibly sub-headings etc.). Objects are tracked sequentially as they relate -to each other object within a document and substantive objects are numbered -sequentially, for citation purposes. Notably footnotes are not objects in -themselves, rather belonging to the object from which they are referenced, and -following their own numbering sequence. From heading objects (linked) tables of -content may be generated, and if additional metadata is provided book type -indexes can be generated that link back to the objects to which they relate. -
- --Unpacking this a bit further. SiSU as a concept independent of its markup -language and the parsers that have been implemented, is based on the following -ideas: -
- --Object-Centricity. On objects: In SiSU objects are the fundamental unit -from which larger constructs within a document and the document itself is built. -Breaking the document into objects provides interesting possibilities. -
- --Objects are fundamental building blocks: Conceptually within SiSU, -objects are the building blocks or individual units of construction of a -document. Objects are usually blocks of text, the most common of which is the -paragraph, other examples include: individual headings, tables, grouped text of -various types which include code blocks and verse within poems, ... and as -mentioned an object could also, for example, be an image. Objects can be -formatted and placed as needed, providing flexibility and enabling multiple -types of representation across disperate formats and text recepticle, examples -including html, epub, latex (in the past mind-maps) and sql (populated at an -object level, and thereby providing search with that degree of granularity). -
--Sequential. Objects have sequence: That objects have sequence, goes -largely without saying, this follows authorship, it is part of the definition of -a document and how a document is written to convey meaning. +The collection contains 25+ documents released under various Creative Commons +licences, in the public domain, or as the author's own work (with one +GPL-licensed exception and the abandoned Debian live-manual). A specialised +collection would benefit from a consistently applied bespoke ontology or +thesaurus.
-
-Object Numbers & Citation. Substantive objects are numbered for citation
-purposes: Most objects within a document are meant by the author to be a
-substantive part of the document. All such objects are numbered sequentially and
-can be referenced thereby for citation purposes.
-
-Object numbers provide the possibility of citing/locating text precisely across
-different document formats and different languages (assuming the document has
-been translated). For search it also makes it possible to identify precisely
-where search criteria is met within in each document in the form of an index or
-to view those precise text objects before deciding which documents are of
-interest. Additionally the use of objects (and that objects are numbered) frees
-the possibility to represent the document in the manner considered most suitable
-to a specific document format wilst retaining its structural (and citation)
-integrity).
-
-Characteristics. Objects have properties and attributes: Objects have -properties (and may have attributes). By properties I here refer to the -fundamental type of object, be it a heading, a paragraph, table, verse etc. -Attributes extend further and may include other things that one might wish to -associate with the object (examples not necessarily currently available/ -implemented in SiSU might include, formatting whether it is indented, or -metadata e.g. the associated language, or programming language for a code block) +All project repositories are at +https://git.sisudoc.org:
-
-Document structure. Heading objects hold documents structure: Heading
-objects hold documents structure through their heading level property. The types
-of document of interest to SiSU have structure that is captured by the heading
-level property. Headings are individual objects like any other with the
-additional properties that (i) they may be regarded as containing the other
-objects following them sequentially (until the next heading of a similar or
-higher level), heading objects may include other headings (sub-headings), and
-(ii) that they have a heirarchy, the root "heading" being the document
-title.
-
-A complication was intruduced to provide greater flexibility across document
-output formats. Headings have two sets of levels, the level under which
-substantive text occurs, this would be a chapter or segment level, and above
-that in the heirarchy if needed are document section separators, book, section,
-part.
-
-Non-objects Most but not all parts of a document are treated as objects. -Notably footnotes are not objects in themselves, rather belonging to the object -from which they are referenced, and following their own numbering sequence. From -heading objects (linked) tables of content may be generated, and if additional -metadata is provided book type indexes can be generated that link back to the -objects to which they relate. -

SiSU document have headers which contain document -metadata, at a minimum the document title and author. In addition the document -header may contain markup instruction (e.g. how to identify headings within the -document, in which case those headings need not be found and treated -accordingly) -
- -
-SiSU parsers have now been implemented in different programming paradigms and
-languages a couple of times, the chosen markup has been left unchanged though
-the document headers have been modified.
-
-This is the core of sisu, beyond which there is more but largely in the form of
-choices based on ... existing output formats and of implementation detail,
-deciding what attributes of objects, or within objects should be supported,
-extending markup to allow for the generation of book indexes from if tagging
-provided.
-
-Here is a description that has been used for the original sisu (scribe): -
- --With minimal preparation of a plain-text (UTF-8) file, using sisu markup syntax -in your text editor of choice, SiSU can generate various document formats, most -of which share a common object numbering system for locating content, including -plain text, HTML, XHTML, XML, EPUB, OpenDocument text (ODF:ODT), LaTeX, PDF -files, and populate an SQL database with objects (roughly paragraph-sized -chunks) so searches may be performed and matches returned with that degree of -granularity. Think of being able to finely match text in documents, using common -object numbers, across different output formats (same object identifier for pdf, -epub or html) and across languages if you have translations of the same document -(same object identifier across languages). For search, your criteria is met by -these documents at these locations within each document (equally relevant across -different output formats and languages). To be clear (if obvious) page numbers -provide none of this functionality. Object numbering is particularly suitable -for "published" works (finalized texts as opposed to works that are frequently -changed or updated) for which it provides a fixed means of reference of content. -Document outputs can also share provided semantic meta-data. -
- --SiSU is less about document layout than it is about finding a way using little -markup to construct an abstract representation of a document that makes it -possible to produce multiple representations of it which may be rather different -from each other and used for different purposes, whether layout and publishing, -scrollworthy online viewing/ reading, or content search. To be able to take -advantage from its minimal preparation starting point of some of the strengths -of rather different established ways of representing documents for different -purposes, whether for search (relational database, or indexed flat files -generated for that purpose whether of complete documents, or say of files made -up of objects), online or other electronic viewing (e.g. html, xml, epub), or -paper publication (e.g. pdf via latex)... -
- --The solution arrived at is to extract structural information about the document -(document sections and headings within the document, available through pattern -matching or markup) and tracking objects (which primarily are defined units of -text such as paragraphs, headings, tables, verse, etc. but also images) which -can be reconstituted as the same documents with relevant object identification -numbers so text (objects) can be referenced across different output formats and -presentations. -
- --SiSU generates tables of content, and through its markup the means for metadata -to be provided for the generation of book style indexes for a document (that -again due to document object numbers are the same and equally relevant across -all document formats). Per document classifying/organizing metadata can also be -provided for automated document curation. -
- --... there have also been working experiments with sisu markup source, two way -conversion/representation of sisu document markup source in mind-mapping -(software kdissert was used for its strong focus on producing documents (now -apparently called semantik)); also po4a software for translators has been used -successfuly in its regular text mode for sisu markup in translation, (which is -more an attribute of po4a than of sisu, but) which is of interest due to -sisu/spine's object citation numbering being available across translations. Open -Document Format text (odf:odt), has been an output, but much more interesting -(and requested by potential users of sisu/spine) would be the ability of a word -processor to save text/a document in sisu markup, making alternative document -processing and presentations with sisu possible. -
- --also worth mention, in the relatively long history of this project, there has -been work done on extracting hash representations of each object, that could -hypothetically be shared to prove the content of a document without sharing its -content, or of identifying which objects change; these hashes can also be used -as unique identifiers in a database or as identifying filenames if individual -objects are saved. -
- -
-SiSU has evolved, the current implementation focuses on one primary use-case,
-books and literary writings. However the concept on which it is based has wider
-application. Here is a prevously posted souvenir from my encounter with an IBM
-software evaluator in London June 2004 that came about through a chance
-encounter with an IBM manager at a Linux Expo, who was curious about my interest
-in Gnu/Linux with my legal background... on hearing that I also wrote software,
-he suggested, maybe IBM should have a look at it. I was interested, the meeting
-was set up... with an IBM, Software Innovations evaluator
-
-His response after the meeting:
-
-"Ralph
Good to meet with you today, I was very impressed with your
-software.
[colleague's name (also posted to an IBM colleague)] - in
-summary - Ralph has built an application that runs on linux and takes ASCII
-documents and pulls them apart in to the smallest constituent parts, storing
-them as XML, PDF and HTML, the HTML are hyperlinked up so the document can be
-browsed in its full form. the format and text data created is stored in a
-database.
This has potential in any place that needs the power of full text
-search whilst holding the structural concepts of the document i.e. legal,
-pharma, education, research.. which ones we need to figure out, ..."
-
-Special interest was expressed in the search implications of SiSU. To -paraphrase, the company has document management systems dealing with hundreds of -thousands of texts, these tell you which documents match your search criteria, -but cannot inform you where within a text these matches were found without -opening the documents. This is achieved through defining document objects and -making them the building block of the document, trackable document objects (that -can be placed back in the context of the document or corpus of documents if part -of a collection). SiSU's early design was to - abstract documents to their -structure, and identified objects, numbered in a citable way (as pointed out -document object hashes can be of use for the purpose). -
- --SiSU Spine is the new generator for documents prepared in sisu markup, written -in D as opposed to the original sisu which was first shared in Ruby. -
+-sisudoc spine code was shared publicly under the AGPLv3 2024-05-01 (after -considerable procrastination). (It should be fairly straightforward to have this -work on other OS platforms, I have only used linux since 1999.) -
- --As compared with the original sisu generator sisu spine: -
- --- Spine uses the same document markup for the document body, but uses yaml for -document headers (which contains document metadata and configuration details), -the original sisu has a bespoke markup for headers. -
- --- Spine (written in D) is considerably faster at generating native output than -sisu (written in Ruby), on last test at least 60 times faster (what took 1 -minute takes 1 second; 1 hour a minute :-) (admittedly some time ago, ruby has -been getting faster, hopefully this is not over over promising). -
- --- Spine produces fewer document outputs types than sisu (html, epub, (odt, -latex) and populates sql db for search) -
- --- As regards non-native output, so far Spine has greater separation of what it -does and largely leaves calling the external program to the user, e.g.: latex -output is a native output in the sense that it is generated directly by spine, -but the pdfs that can be produced from these are produced through use of an -external program xelatex, which produces fine output but is a very much slower -process. -
- --- (where both produce the same output type, generally) Spine generally produces -more up to date output format representations. -
- --SiSU is more suited to finalized/stratified/published writings (writings, -articles, books), that are to remain and be referenced as published, -representing a work or ideas, set at a given time. (As opposed to the -increasingly prevalent and important forms of fluid text). -
- --Trained AI likely could assist in the preparation of documents (with SiSU -markup), with resulting deterministic and reproducible outputs (for substantive -document objects). Caveats: Where text objects may be in blocks (or not) there -is some room for discretion and ambiguity in the markup with resulting -possibility of differences in the resulting presentation of a document. Book -indexes are another area that if desired is markup intensive and unless -following an already published index, can be prepared differently and possibly -improved over time, and for specialised collections on a subject area could -potentially be prepared against a thesaurus. -
- --Thanks to all who help produce and maintain the software and libraries I am able -to use and have come to rely on. Reliable infrastructure so far. +Spine (D) and the original sisu (Ruby) share the same lightweight body markup; +spine moves the document header to YAML where the original uses a bespoke header +dialect. Spine is roughly 60x faster on equivalent inputs (a one-minute Ruby run +is about a one-second D run). Spine emits HTML, EPUB, LaTeX, ODT, plain text and +the SQLite search database; PDF is delegated to an external xelatex pass (slower +but produces excellent output). For output formats both produce, spine's +representations are generally more up to date. Spine was released publicly under +AGPLv3 on 2024-05-01.

-SiSU is an object-centric, lightweight markup based, document structuring, -parser, publishing and search tool for document collections. It is command line -oriented and generates static content that is currently made searchable at an -object level through an SQL database. -Markup helps define (delineate) objects (primarily various types of text block) -which are tracked in sequence, substantive objects being numbered sequentially -by the program for object citation. -
- --Summary. An object is a unit of text within a document the most common -being a paragraph. Objects include individual headings, paragraphs, tables, -grouped text of various types such as code blocks and within poems, verse. -Objects have properties and attributes, of particular significance are headings -and their levels which provide document structure. A heading is an object with a -heirarchical value, that conceptually contains other objects (such as paragraphs -and possibly sub-headings etc.). Objects are tracked sequentially as they relate -to each other object within a document and substantive objects are numbered -sequentially, for citation purposes. Notably footnotes are not objects in -themselves, rather belonging to the object from which they are referenced, and -following their own numbering sequence. From heading objects (linked) tables of -content may be generated, and if additional metadata is provided book type -indexes can be generated that link back to the objects to which they relate. -
- --Unpacking this a bit further. SiSU as a concept independent of its markup -language and the parsers that have been implemented, is based on the following -ideas: -
- --Object-Centricity. On objects: In SiSU objects are the fundamental unit -from which larger constructs within a document and the document itself is built. -Breaking the document into objects provides interesting possibilities. -
- --Objects are fundamental building blocks: Conceptually within SiSU, -objects are the building blocks or individual units of construction of a -document. Objects are usually blocks of text, the most common of which is the -paragraph, other examples include: individual headings, tables, grouped text of -various types which include code blocks and verse within poems, ... and as -mentioned an object could also, for example, be an image. Objects can be -formatted and placed as needed, providing flexibility and enabling multiple -types of representation across disperate formats and text recepticle, examples -including html, epub, latex (in the past mind-maps) and sql (populated at an -object level, and thereby providing search with that degree of granularity). -
--Sequential. Objects have sequence: That objects have sequence, goes -largely without saying, this follows authorship, it is part of the definition of -a document and how a document is written to convey meaning. +The collection contains 25+ documents released under various Creative Commons +licences, in the public domain, or as the author's own work (with one +GPL-licensed exception and the abandoned Debian live-manual). A specialised +collection would benefit from a consistently applied bespoke ontology or +thesaurus.
-
-Object Numbers & Citation. Substantive objects are numbered for citation
-purposes: Most objects within a document are meant by the author to be a
-substantive part of the document. All such objects are numbered sequentially and
-can be referenced thereby for citation purposes.
-
-Object numbers provide the possibility of citing/locating text precisely across
-different document formats and different languages (assuming the document has
-been translated). For search it also makes it possible to identify precisely
-where search criteria is met within in each document in the form of an index or
-to view those precise text objects before deciding which documents are of
-interest. Additionally the use of objects (and that objects are numbered) frees
-the possibility to represent the document in the manner considered most suitable
-to a specific document format wilst retaining its structural (and citation)
-integrity).
-
-Characteristics. Objects have properties and attributes: Objects have -properties (and may have attributes). By properties I here refer to the -fundamental type of object, be it a heading, a paragraph, table, verse etc. -Attributes extend further and may include other things that one might wish to -associate with the object (examples not necessarily currently available/ -implemented in SiSU might include, formatting whether it is indented, or -metadata e.g. the associated language, or programming language for a code block) +All project repositories are at +https://git.sisudoc.org:
-
-Document structure. Heading objects hold documents structure: Heading
-objects hold documents structure through their heading level property. The types
-of document of interest to SiSU have structure that is captured by the heading
-level property. Headings are individual objects like any other with the
-additional properties that (i) they may be regarded as containing the other
-objects following them sequentially (until the next heading of a similar or
-higher level), heading objects may include other headings (sub-headings), and
-(ii) that they have a heirarchy, the root "heading" being the document
-title.
-
-A complication was intruduced to provide greater flexibility across document
-output formats. Headings have two sets of levels, the level under which
-substantive text occurs, this would be a chapter or segment level, and above
-that in the heirarchy if needed are document section separators, book, section,
-part.
-
-Non-objects Most but not all parts of a document are treated as objects. -Notably footnotes are not objects in themselves, rather belonging to the object -from which they are referenced, and following their own numbering sequence. From -heading objects (linked) tables of content may be generated, and if additional -metadata is provided book type indexes can be generated that link back to the -objects to which they relate. -

SiSU document have headers which contain document -metadata, at a minimum the document title and author. In addition the document -header may contain markup instruction (e.g. how to identify headings within the -document, in which case those headings need not be found and treated -accordingly) -
- -
-SiSU parsers have now been implemented in different programming paradigms and
-languages a couple of times, the chosen markup has been left unchanged though
-the document headers have been modified.
-
-This is the core of sisu, beyond which there is more but largely in the form of
-choices based on ... existing output formats and of implementation detail,
-deciding what attributes of objects, or within objects should be supported,
-extending markup to allow for the generation of book indexes from if tagging
-provided.
-
-Here is a description that has been used for the original sisu (scribe): -
- --With minimal preparation of a plain-text (UTF-8) file, using sisu markup syntax -in your text editor of choice, SiSU can generate various document formats, most -of which share a common object numbering system for locating content, including -plain text, HTML, XHTML, XML, EPUB, OpenDocument text (ODF:ODT), LaTeX, PDF -files, and populate an SQL database with objects (roughly paragraph-sized -chunks) so searches may be performed and matches returned with that degree of -granularity. Think of being able to finely match text in documents, using common -object numbers, across different output formats (same object identifier for pdf, -epub or html) and across languages if you have translations of the same document -(same object identifier across languages). For search, your criteria is met by -these documents at these locations within each document (equally relevant across -different output formats and languages). To be clear (if obvious) page numbers -provide none of this functionality. Object numbering is particularly suitable -for "published" works (finalized texts as opposed to works that are frequently -changed or updated) for which it provides a fixed means of reference of content. -Document outputs can also share provided semantic meta-data. -
- --SiSU is less about document layout than it is about finding a way using little -markup to construct an abstract representation of a document that makes it -possible to produce multiple representations of it which may be rather different -from each other and used for different purposes, whether layout and publishing, -scrollworthy online viewing/ reading, or content search. To be able to take -advantage from its minimal preparation starting point of some of the strengths -of rather different established ways of representing documents for different -purposes, whether for search (relational database, or indexed flat files -generated for that purpose whether of complete documents, or say of files made -up of objects), online or other electronic viewing (e.g. html, xml, epub), or -paper publication (e.g. pdf via latex)... -
- --The solution arrived at is to extract structural information about the document -(document sections and headings within the document, available through pattern -matching or markup) and tracking objects (which primarily are defined units of -text such as paragraphs, headings, tables, verse, etc. but also images) which -can be reconstituted as the same documents with relevant object identification -numbers so text (objects) can be referenced across different output formats and -presentations. -
- --SiSU generates tables of content, and through its markup the means for metadata -to be provided for the generation of book style indexes for a document (that -again due to document object numbers are the same and equally relevant across -all document formats). Per document classifying/organizing metadata can also be -provided for automated document curation. -
- --... there have also been working experiments with sisu markup source, two way -conversion/representation of sisu document markup source in mind-mapping -(software kdissert was used for its strong focus on producing documents (now -apparently called semantik)); also po4a software for translators has been used -successfuly in its regular text mode for sisu markup in translation, (which is -more an attribute of po4a than of sisu, but) which is of interest due to -sisu/spine's object citation numbering being available across translations. Open -Document Format text (odf:odt), has been an output, but much more interesting -(and requested by potential users of sisu/spine) would be the ability of a word -processor to save text/a document in sisu markup, making alternative document -processing and presentations with sisu possible. -
- --also worth mention, in the relatively long history of this project, there has -been work done on extracting hash representations of each object, that could -hypothetically be shared to prove the content of a document without sharing its -content, or of identifying which objects change; these hashes can also be used -as unique identifiers in a database or as identifying filenames if individual -objects are saved. -
- -
-SiSU has evolved, the current implementation focuses on one primary use-case,
-books and literary writings. However the concept on which it is based has wider
-application. Here is a prevously posted souvenir from my encounter with an IBM
-software evaluator in London June 2004 that came about through a chance
-encounter with an IBM manager at a Linux Expo, who was curious about my interest
-in Gnu/Linux with my legal background... on hearing that I also wrote software,
-he suggested, maybe IBM should have a look at it. I was interested, the meeting
-was set up... with an IBM, Software Innovations evaluator
-
-His response after the meeting:
-
-"Ralph
Good to meet with you today, I was very impressed with your
-software.

-documents and pulls them apart in to the smallest constituent parts, storing
-them as XML, PDF and HTML, the HTML are hyperlinked up so the document can be
-browsed in its full form. the format and text data created is stored in a
-database.
This has potential in any place that needs the power of full text
-search whilst holding the structural concepts of the document i.e. legal,
-pharma, education, research.. which ones we need to figure out, ..."
-
-Special interest was expressed in the search implications of SiSU. To -paraphrase, the company has document management systems dealing with hundreds of -thousands of texts, these tell you which documents match your search criteria, -but cannot inform you where within a text these matches were found without -opening the documents. This is achieved through defining document objects and -making them the building block of the document, trackable document objects (that -can be placed back in the context of the document or corpus of documents if part -of a collection). SiSU's early design was to - abstract documents to their -structure, and identified objects, numbered in a citable way (as pointed out -document object hashes can be of use for the purpose). -
- --SiSU Spine is the new generator for documents prepared in sisu markup, written -in D as opposed to the original sisu which was first shared in Ruby. -
+-sisudoc spine code was shared publicly under the AGPLv3 2024-05-01 (after -considerable procrastination). (It should be fairly straightforward to have this -work on other OS platforms, I have only used linux since 1999.) -
- --As compared with the original sisu generator sisu spine: -
- --- Spine uses the same document markup for the document body, but uses yaml for -document headers (which contains document metadata and configuration details), -the original sisu has a bespoke markup for headers. -
- --- Spine (written in D) is considerably faster at generating native output than -sisu (written in Ruby), on last test at least 60 times faster (what took 1 -minute takes 1 second; 1 hour a minute :-) (admittedly some time ago, ruby has -been getting faster, hopefully this is not over over promising). -
- --- Spine produces fewer document outputs types than sisu (html, epub, (odt, -latex) and populates sql db for search) -
- --- As regards non-native output, so far Spine has greater separation of what it -does and largely leaves calling the external program to the user, e.g.: latex -output is a native output in the sense that it is generated directly by spine, -but the pdfs that can be produced from these are produced through use of an -external program xelatex, which produces fine output but is a very much slower -process. -
- --- (where both produce the same output type, generally) Spine generally produces -more up to date output format representations. -
- --SiSU is more suited to finalized/stratified/published writings (writings, -articles, books), that are to remain and be referenced as published, -representing a work or ideas, set at a given time. (As opposed to the -increasingly prevalent and important forms of fluid text). -
- --Trained AI likely could assist in the preparation of documents (with SiSU -markup), with resulting deterministic and reproducible outputs (for substantive -document objects). Caveats: Where text objects may be in blocks (or not) there -is some room for discretion and ambiguity in the markup with resulting -possibility of differences in the resulting presentation of a document. Book -indexes are another area that if desired is markup intensive and unless -following an already published index, can be prepared differently and possibly -improved over time, and for specialised collections on a subject area could -potentially be prepared against a thesaurus. -
- --Thanks to all who help produce and maintain the software and libraries I am able -to use and have come to rely on. Reliable infrastructure so far. +Spine (D) and the original sisu (Ruby) share the same lightweight body markup; +spine moves the document header to YAML where the original uses a bespoke header +dialect.
